摘要：The invention concerns a method for managing an assisted steering system (1) for a vehicle, said assisted steering system including at least one assistance function (F1) intended to help a driver drive the vehicle and at least one safety function (F2) intended to give said assistance function a predetermined ASIL level as defined by the ISO-26262 standard, said assistance function and said safety function each making use of a vehicle speed indicator parameter (V_param), said method comprising a step (a) of estimating a functional speed (V_func) representative of the actual longitudinal speed of the vehicle, used by default as the vehicle speed indicator parameter (V_param), a step (b) of estimating a speed upper bound (V_upper), a step (c) of calculating an underestimated speed (V_under) resulting from the application, to the speed upper bound (V_upper), of a reduction value (V_reduc) derived from a reduction law (LR), and, if the functional speed (V_func) is lower than the underestimated speed (V_under), a step (e) of switching in which the underestimated speed (V_under) is substituted for the functional speed (V_func) as the vehicle speed indicator parameter (V_param).
